Worked examples

Specific situations worked through end to end: the credit position, what a lender sees, what the deal costs at published tier averages, and what to do next. These are illustrations built from public rate data, not quotes.

Active Duty, PCS Orders: Selling a Financed Car FastA worked example: 21 days to report, $18,500 owed, car worth $14,000 to $15,500. Rolling the $4,500 gap into a new loan adds $2,896 in interest.
Avoiding a Second Underwater Loan After PayoffA worked example: a car loan paid off after 6 years underwater, credit improved to 495, $3,000 saved. Comparing 2 structures for the next loan.
In a Buy Here Pay Here Loan, 14 Months In, Wants to Refinance14 months of on-time payments at a buy-here-pay-here lot that doesn't report. Refinancing to 21.6% from a 25.4% weighted average saves $18 a month.
BHPH Deferred Down Payment Turned Into a Repo RiskA worked example: a $700 pickup payment lands the same week as the regular payment. What to fix first, and how to keep the car, in 5 steps.
BHPH Loan Falling Behind: What Now?A worked example: one or two missed BHPH payments, a non-reporting lot, and a realistic path forward. Refinancing out can save $46 a month once caught up.
Not Enough Saved for a Down Payment, Considering BHPHWith only $400 saved, BHPH looks easier to get into. But at 25.4% APR versus 14.6%, that path costs $2,571 more than waiting to save $1,000 down.
Building Credit From Zero Before a First Car PurchaseA worked example: waiting 3 to 4 months to build a thin file before financing. On $10,000, that can mean $274 a month instead of $296 — $22 saved.
Car Died, Need Something in 48 Hours, 520 ScoreA worked example: $800 saved, a 520 score, no working vehicle. What urgency costs, what to do when you cannot wait, and what to refuse anyway.
Car Totaled, No GAP Insurance, Still Owe $4,000A worked example: insurance paid the car's value, $4,000 is still owed. Rolling that shortfall into a new loan costs $2,574 more than paying it separately.
Tempted by a Cash-Out Refinance, But Probably Shouldn't BeA cash-out refinance for an unrelated bill sounds simple, but $6,000 pulled out at 21.6% APR over 60 months costs $9,861 to pay back in total.
Chapter 7 Discharged Three Months AgoA worked example: Chapter 7 discharged 90 days ago, 540 score, $2,000 down. What the discharge order unlocks and what the deal costs at 18.86%.
Old Auto Charge-Off, Medical Collections, 560 Credit ScoreA years-old charge-off, two medical collections, and a 560 score, with 1 year of clean payments since. What actually blocks this deal, and what doesn't.
College Student, Part-Time Job, $1,100 a MonthA worked example: $1,100 gross income, no cosigner. The 15% to 20% PTI cap allows $165 to $220 a month — the honest math for what that actually buys.
Cosigner Wants Off the Loan After Two YearsA worked example: cosigner wants off after 24 months of clean payments. Refinancing solo at 14.6% instead of 21.6% saves $32 a month on $9,000 owed.
Credit Score Improved, Loan 13 Months In: Time to Refinance?A worked example: deep-subprime buyer, 13 months of on-time payments, score moved to subprime. Refinancing toward 11.43% could save about $63 a month.
Deciding to Wait Six Months and Rebuild FirstA worked example: qualifying today versus waiting six months to rebuild. A tier jump on $14,000 financed saves $53 a month, but waiting has real costs too.
Divorced and the Car Loan Is Still JointA divorce decree does not bind the lender — both names stay liable until refinanced. On $14,000, refinancing alone at 18.86% costs $34 a month more.
First Car, No Credit History, 22 Years OldA worked example: no credit file at 22, $2,400 a month, $1,200 saved. Why no file is not a bad file, and why a cosigner is worth $50 a month.
First-Time Buyer Choosing BHPH vs. WaitingA worked example: no credit file, a BHPH car available now, or 4 to 6 months building credit first. The wait can save about $2,485 in interest.
First-Time Buyer Fell for a Dealer Add-On TrapA first-time buyer financed $2,700 of add-ons into a 72-month loan — $68 a month extra. Canceling the weakest one can start reversing it.
Gig Worker, No W-2, 620 Credit ScoreA worked example: $3,800 a month from rideshare, no pay stubs, 620 score. The score is fine at 14.11% — the income documents are the whole problem.
Just Got a First Full-Time Job, No Cosigner AvailableA worked example: first full-time job at $2,800 a month, a 10-month-old secured card, no cosigner. Why the credit union reads this file differently.
Married, Spouse Has the Income, I Have the Credit ProblemA worked example: one spouse at 790, one at 505, deciding solo vs. joint. On $17,000, applying solo could mean $331 a month instead of $466.
Active Duty E-4, First Duty Station, No Credit HistoryA worked example: $2,800 a month, no credit file, a dealer outside the gate. On $14,000, 21.58% is $383 a month against $327 at 14.11%.
New Immigrant, ITIN, No US Credit HistoryA worked example: ITIN instead of an SSN, no US credit file, $2,700 a month. On $11,000 financed at 21.6%, the payment runs about $301 over 60 months.
No Cosigner Available, 540 Credit ScoreQualifying solo at a 540 score is realistic without a cosigner. On a $14,000 car with $2,000 down, financing $12,000 at 21.6% runs $329 a month.
Buying a Car on SSDI or Disability Income, $1,600 a MonthA $1,600 SSDI income caps the payment near $240 to $320 a month. Here's what that buys at 21.6% APR, and why waiting can beat stretching.
Paid in Cash, No Paper Trail, Need a CarCash income is a documentation problem, not a character one. Starting a bank deposit history now is step one; $11,000 financed at 21.6% runs $301 a month.
A Parent Cosigning for a First-Time Buyer: A Worked ExampleA 20-year-old's thin file alone could mean 21.6% or worse. With a parent cosigning at 11.43%, illustratively, the payment drops $71 a month on $13,000.
Repossessed Last Year, Deficiency Balance Still OpenA worked example: repo 12 months ago, deficiency unresolved, 510 score, $2,750 income. The open balance blocks approval more than the score does.
Repossession Two Years Ago, 480 Credit ScoreA worked example: repossession 24 months back, deficiency settled, 480 score, $2,600 income. What lenders see, what the deal costs, and what to fix first.
Rideshare Driver Needs a Newer Car to Stay EligibleA worked example: full-time rideshare, 1099 income, 515 score, aging car past the platform's age limit. Financing $15,500 at 21.6% runs $425 a month.
Saved Six Months for a Bigger Down Payment: Was It Worth It?A worked example: waiting six months to go from $1,000 to $2,500 down on a $14,000 car saves $41 a month and $966 in interest — but waiting has real costs too.
1099 Contractor Who Writes Off Everything, 640 ScoreA worked example: $6,000 gross, $2,900 net after Schedule C write-offs, 640 score. Why deductions cut what you can finance from $38,600 to $18,600.
Selling the Car Privately to Clear Negative EquitySelling a car privately and paying the payoff gap in cash usually beats rolling it into a new loan. Financing $4,500 more at 21.6% adds $124 a month.
Settled the Deficiency, Rebuilding at 560A worked example: deficiency settled in writing, 560 score, $3,000 income. A $10,000 loan at 18.86% runs $259 a month — and refinances at month 12.
Single Parent, $2,200 a Month, Needs a Reliable CarA worked example: $2,200 gross, 560 score, $1,400 down. The 15% to 20% PTI cap allows $330 to $440 — but the childcare line sets the real budget.
Still in Chapter 13, Need a CarFinancing while in an active Chapter 13 plan generally needs trustee approval first. A worked example: $11,500 financed at 21.6% runs $315 a month.
Two Part-Time Jobs, Thin File, 590 Credit ScoreA worked example: $3,100 a month from two part-time jobs, a 590 score, $1,500 down. Why two income sources are harder to verify than one.
Two Repossessions on Record, Rebuilding From ScratchA worked example: two repossessions, one settled, one open. On $9,800 financed at 21.6%, the payment runs $268 a month — the deficiency is the real block.
Underwater $7,000 and Want to Trade UpA worked example: $19,000 owed on a $12,000 car, 580 score. Rolling the $7,000 forward costs $11,742 to retire $7,000. Here is the math.
